Emmenopterys henryi in Europe
The first introduction to Europe was 1907 to England by Ernest Wilson. They are noted for their rare flowering. The first time that Emmenopterys henryi flowered in mainland Europe was 1971 in the arboretum of Villa Taranto on Lago Maggiore. A specimen in Cambridge flowered in 2012, after 30 years, only the fifth flowering in the UK. In 2013, a tree flowered for the fourth time in the Arboretum Kalmthout in Belgium. This was unexpected, since the flowers only appeared in September, which is quite late.
